Not sure who is entertained more by the exersaucer, the 2 month old, the 2.5 yr old or the almost 4 yr old. DD3 will stay in the exersaucer for at least 20 mins if her older sisters are sitting around her playing with all the attachments. Once she starts getting fussy I take her out and the older 2 girls will continue to play for a good half hour. Thankful a friend of a friend was kind enough to give it to me. Lots of entertainment over here!
